On my laptop with Office 2010, I get an error every time I install/update Daniel's XL toolbox. It says something like "object cannot be found..."
From the forums,
it says to uncheck any references listed as "missing." I have none. What seems to work though is simply saving the macro.
In excel hit alt+F11 to open the macro editor. Highlight Daniel's XL toolbox in the tree. Click the save button. That's it.
The first time I had this happen, I spend hour(s) trying to find the solution and ended up finding a forum that had me delete something out of the tree and saving...it worked but I can't find the forum. It was supposed to rebuild something in the macro and save it. Since I saved it, it might have been the only key.
